Abstract

A computational fluid dynamics (CFD) model is used to simulate a stable wind blowing over slope beds of varying height and coupled with the slope-compensating fluid threshold friction velocity formula. Based on the CFD-based model, quantitative analyses of slope gradient and particle position on the initiation of particle movement are performed. Results indicate that the slope has a great influence on particle saltation in the windward slope, and the initiation of particle movement is particularly sensitive to particle position with respect to the slope
